Weblogic 不會關閉文件（但會關閉連接）

親愛的，

我們遇到了“打開的文件太多”的問題。

我們已經取得了一些進展，但問題仍然存在……

我們在 aix 上的 weblogic 上使用 cxf。

相關的 cxf 配置：

<http-conf:conduit name="*.http-conduit">
   <http-conf:client Connection="close" />
</http-conf:conduit>

執行此程式碼時：

       for(int i=0;i<1300;i++){
           response = callService(request).call();
       }

（我們不打算在生產中使用此程式碼，但它是為了解決問題）

-> 第一次執行成功；

-> 第二次執行暴露了問題

輸出：

  netstat| wc -l

首先表明有太多的套接字仍然打開（因此 cxf 配置更改）

現在打開的套接字保持穩定 +- 400 行，在配置更改之前 >1000

但…

lsof 2> /dev/null|grep TCP|wc -l

暴露了我們目前遇到的問題

打開的套接字的數量是穩定的（所以套接字被關閉）但打開的文件的數量不是……

從託管伺服器啟動後的 319 到引發以下異常時的 +-1688：

如果要提供更多資訊，請詢問，

非常感謝您對解決此問題的任何幫助，

重新啟動託管伺服器“解決”了問題，但這不是生產中的選項……

TIME_WAIT 設置為 1（15 秒），所以沒有解決方案……

S。

這似乎是那個版本的 CXF 中的一個錯誤（我嘗試並在 3.0.4 和 3.0.12 中都發現了這個問題）。將 CXF 降級到 2.6.2 為我解決了這個問題。（我沒有在 3.1.x 版本中嘗試過。）
